I also could not find any. I wonder if it has something to do with personas.

Engineers and tech people tend to be terminally online and often spend a large amount of time in front the screen, whereas markerters and sales use tech for enablement only and rather spend in person. I could be wrong but this is my observation.

The marketers use tech to converse too to learn ways to better their craft. You see them on the subreddits as I mentioned in my original comment.
